The limit groove is provided corresponding to the limit block 162, and the limit groove is connected to the limit block 162 to lock the side plate 165. The chamfer improves the smoothness of the limit groove sliding into the limit block 162 when the side plate 165 moves to the limit block 162.

[0044] Positioning grooves 171 are provided at both ends of the inspection platform 16. The positioning grooves 171 are located below the groove 17 and below the inspection platform 16. A convex rib 172 is fixed in the horizontal through groove 18. The convex rib 172 is arranged on both sides of the groove 17. A material blocking assembly 4 is installed in the end groove 164.

[0045] like Figure 5-Figure 8 As shown, the material blocking assembly 4 includes a base frame 41, which is horizontally fixedly mounted on cylinder 2 42, and end plates 43 are provided at both ends of the base frame 41. The end plate 43 close to the test device 2 is fixedly connected to the base frame 41, and the other end plate 43 is vertically inserted into the base frame 41. The end plate 43 is vertically slid into the end groove 164. When the end plate 43 moves upward, it can limit and fix the groove 17 and the material to be inspected on the inspection table 16. A positioning block 44 is fixedly mounted on one side of the end plate 43, and the positioning block 44 is located between the two end plates 43.

[0046] A top groove 45 is provided on the end plate 43, and the end plate 43 fixedly mounted on the base frame 41 has the following structure: an L-shaped groove 46 is provided below the top groove 45, and a pusher 5 is slidingly provided in the L-shaped groove 46, and an axis frame 47 is riveted on the outer side of the end plate 43, and a circular shaft is horizontally rotated on the axis frame 47, and a rotating member 48 is fixedly mounted on the circular shaft, and a pressure plate 481 is fixedly provided on the rotating member 48, and when the pressure plate 481 is horizontally located in the top groove 45, it can press the materials to be inspected in the groove 17 and the inspection table 16, and when the pressure plate 481 leaves the top groove 45, it is unlocked and fixed.

[0047] A limiting plate 482 is welded on the pressure plate 481, and a limiting rod 471 is inserted on the shaft frame 47. The limiting rod 471 is horizontally fixed on the shaft frame 47. When the limiting plate 482 on the pressure plate 481 rotates to a horizontal position, it interferes with the limiting rod 471, thereby limiting and fixing the limiting plate 482 and the pressure plate 481. A coaxially arranged gear 472 is fixed on the circular shaft, and the gear 472 is located above the L-shaped groove 46.

[0048] A return spring 461 is sunken on the inner side of the L-shaped groove 46 near the material blocking assembly 4. The elastic force of the return spring 461 can maintain the tendency of the two pushing members 5 to move toward each other. When the material to be inspected moves toward and pushes the pushing member 5 into the L-shaped groove 46, the return spring 461 is continuously pressurized and the elastic force is accumulated. After the inspection is completed and the material to be inspected is removed, the elastic force is released to push out the pushing member 5.

[0049] The pushing member 5 is an L-shaped structure, which is matched with the L-shaped groove 46. A rack 51 is provided on the pushing member 5, and the rack 51 is engaged with the gear 472. A contact block 52 is fixed at one end of the pushing member 5. One side of the contact block 52 is connected to the reset spring 461, and the other side contacts the material to be inspected.

[0050] like Figures 9-11As shown, the gantry 3 includes a vertical frame 31, which is fixed to the machine base 1 at the bottom by bolts, and an electric slide 1 32 is fixedly installed on the vertical frame 31 by bolts, and an electric slide 2 33 is fixedly installed on the driving slider of the electric slide 1 32. The electric slide 1 32 and the electric slide 2 33 are vertically arranged to form a cross slide moving system, which controls the detection equipment to move in the X-axis and Z-axis directions. The Y-axis direction is the length direction of the groove 17, which is the loading and unloading direction of the material to be inspected.

[0051] The two electric slides are model KK86-150 and KK86-250 respectively.

[0052] A motor frame 34 is fixedly connected to the driving slider of the electric slide 2 33, and a bracket 35 is fastened to one end of the motor frame 34. A guide groove 37 is fixedly provided on the bracket 35, and the guide groove 37 is an inverted V structure. A detection component 6 is slidingly provided in the guide groove 37. A driving motor 36 is fixedly provided on the motor frame 34, and the output shaft of the driving motor 36 faces the bracket 35. The bracket 35 is located in the output direction of the driving motor 36 and has a rotating shaft 361 that rotates, and the rotating shaft 361 is connected to the output shaft of the driving motor 36.

[0053] Swing arms 362 are fixedly provided at both ends of the rotating shaft 361, and straight slots 363 are opened on the swing arms 362. A locking cylinder 38 is fixedly installed on the top of the motor frame 34. The output end of the locking cylinder 38 is fixedly connected to two symmetrically distributed locking shafts 39 to lock the detection component 6.

[0054] The detection component 6 includes a mounting shaft 61, which is slidably installed in the guide groove 37. A locking hole is provided at one end of the mounting shaft 61, and a mounting block 63 is rotatably provided at the other end. When the locking hole is adjusted to the working position, the locking hole is connected and fixed by the locking shaft 39. Two baffles 62 are fixed on the mounting shaft 61, and the baffles 62 are located on both sides of the bracket 35. The mounting shaft 61 is slidably connected to a straight groove 363, and the other straight groove 363 is slidably connected to the mounting block 63.

[0055] A support 64 is fixedly provided on the outer side of the mounting block 63, a sleeve 65 is welded on the support 64, a push rod 66 slides in the sleeve 65, one end of the push rod 66 is fixedly provided with a pressure sensor, the model of the pressure sensor is FSR-A406, and the other end is connected to a compression spring 69, which is fixedly connected to the top of the sleeve 65, an electromagnet 1 67 is fixed on the sleeve 65, and an electromagnet 2 68 is fixed on the push rod 66, and the electromagnet 1 67 and the electromagnet 2 68 are arranged correspondingly. When power is on, the two attract each other, controlling the push rod 66 to move downward, and performing a pressure test on the material to be inspected. When power is off, the compression spring 69 releases the restriction, releases the stored elastic force, and resets the push rod 66.

[0056] A connecting plate 151 is fixed to the output end of the cylinder 15 , and a supporting plate 152 is fixed to one side of the connecting plate 151 . A notch 153 is formed on the supporting plate 152 . When the notch 153 moves to the top on the supporting plate 152 , the notch 153 is connected to the rib 172 .

[0057] During actual testing, the high-voltage incoming line cabinet body or the produced cabinet panel is tested. If it is a cabinet body, one end panel of the cabinet body does not need to be installed. The cabinet body is placed in the groove 17, and the corner of the cabinet body contacts the bottom of the groove 17. At this time, the two pushers 5 are located in the groove 17. The cabinet body contacts the pusher 5 until the end of the cabinet body contacts the end plate 43 on which the pusher 5 is installed. At this time, the other end plate 43 is inserted to fix the cabinet body, and then the test device 2 is manually operated for testing, and then the pressure resistance of the cabinet panel is tested using the pusher 66 on the detection component 6. When the pusher 66 squeezes the cabinet body, the pressure sensor senses the pressure and detects the pressure in real time and intelligently.

[0058] If it is a cabinet panel, the inspection process is the same as the above-mentioned cabinet body inspection. The difference is that before the inspection, it is necessary to increase the height of the pusher 5 and the end plate 43, and move the pusher 5 on the end plate 43 to above the upper surface of the inspection table 16 to prevent the end of the plate from contacting the pusher 5. Then, the cylinder 3 163 pushes the side plate 165 to fix the side of the plate, and lifts the support plate 152 until the top of the support plate 152 contacts the bottom of the cabinet panel to support the cabinet panel for subsequent cabinet panel testing.
